When applying plunger pumps at 1,000psi to 15,000psi, pressure pulsation interception is advisable from PulseGuard. Constant pressure and flow with packed plunger pumps, The high volumetric efficiency of a packed plunger pump, with minimal dead volume in the pump chamber, (Unlike a diaphragm pump,) the level of pulsation is already small, and lack any "lost motion" reduces shock generation; a small flow-through PulseGuard. damper kills the remainder.
Pulsation dampeners that are used with plunger pumps:
